CARBUBETOR.

Application led June 12,

The invention relates to the construction and operation of an apparatus for vaporizing a liquid. n 't q Another object of the Invention is to provide a carburetor for the effective vaporization of liquid :fuel and the formation of a combustible mixture for use in internal combustion. engines.

The invention possesses other advantale geous features, some of which, with the foregoing, will be set forth at length 1n the following description where I shall outline 1n full, `the process of my invention and that form of apparatus for carryingitinto effect which I have selected for illustration in the drawing accompanying ,and forming part of the present specification. In said drawing I have shown one form of apparatus embody;

ing my invention, but vit is to be understood that I do' not limit myself to such form, since the invention, as set forth in the claim, may be embodiedfin a plurality of forms.

The drawing is a vertical section somewhat diagrammatic, of a carburetor embodymg the features of my invention.

The invention comprises the passage of the gas through a body of the liquid in such manner that the liquid isV driven by and with the gas against aA baille late which breaks the liquid into finely divlded particles, thus exposing a very large surface area of the'hquid to the gas. The as is introduced into the liquid through a re atively large conduit so that no delicate or finely adjusted control means are necessary. This is particularly advantageous in a carburetor for produclng combustible mixtures since it eliminates the use of small orifices which become enlarged by wear or irregular by corrosion and the usual needle valve which controls the ilow of the gasoline or other liquid fuel. Further, the carburetor of my invention provides for a much larger surface exposure of the gasoline te the air, thus rendering Carburation more complete and eicient.

In accordance with my inventionv I provide a vessel 2 enclosing a carbureting chamber 3 into which the liquid to be vaporized is introduced through the pipe 4. The level of the liquid in the chamber 1s maintained substantially constant by any suitable or well known means, such as the float 10 disposed in the 'float chamber 5 and controlling the inlet valve 6. The float chamber is con- Cil 1922. serial No. 567,732.

nected, above the float, to the Carburation chamber 3, to equalize the pressure on the float.

Arranged in the chamber 3, and substantially entirely submerged in the liquid therein, is a vertically disposed, open ended conduit 7 preferably conical in shape, with the smaller end of the cone slightly above the level of the liquid. Opening centrally of the cone is a vertically disposed conduit 8, through which air is introduced. The conduit 8 is connected to a vertically disposed intake pipe 9 rising above the level of the liquidl in the chamber 3 for obvious reasons. The passage of air through the pipe 9 is controlled by the adjustable valve 12. The reduction in pressure in the chamber 3, caused by the operation of the internal combustion engine, to the intake manifold of which the chamber 3 is connected, causes a flow of air through the conduit 8. This air, discharging within the cone 7, produces an injector effect, carrying liquid upward with it and striking against the baille plate 13 disposed within the chamber 3 directly above the cone. The liquid is broken up into a spray by impact with the baille plate and the air contacts with a very large surface of the liquid,

in the chamber above the liquid therein, thus producing a rich mixture of comminuted liquid, vapor and air. The richness of the mixture may be controlled by varying the force of impact of the liquid against the baiiie plate and this may be accomplished by varying the spacing between the cone and the baille( For this purpose the baille is arranged on a threaded stem 15 extending through the top wall of the casing, rotatlonof the stem-serving to vary the height of the baille. On account of the violent agitation and comminution of the liquid, it is possible that some large particles of the liquid will be carried from the chamber 3 1n the rapidly moving gaseous mixture. entry of these particles into the cylinders of the internal combustion engine, I prefer to pass the mixture through a helical coil 16, wherein the heavier and larger particles are deposited `on the side walls, by centrifugal force and drain back into the chamber 3.

To produce a combustible mixture of the proper or desired characteristics, air may be added to the rich mixture, thorugh the valve controlled conduit 17 and the resultant mix- To prevent the` ture agitated by the cone 18 to prevent stratification and introduced into the intake manifold of the internal combustion engine.

While I have described my invention as applying to a device for producing a combustible mixture of air and liquid hydrocarbon, it is to be understood that it is not limited to such use but ma be employed to producea mixture of any 'quid vapor and any gas. .A

I claim A carburetor comprising a cylindrical container provided midway between its top and bottom with an inverted funnel carried by l5 a web member integral with said container, a

U-shaped conduit tainer, one end of which terminates Within said inverted funnel while the other end islfy connected tovan upstandingintakejpipe adjacent said container, above said inverted funnel and adjustably Secured to the top of the container by means of a threaded stem operable from without the container, a constant level liquid intake means, and a tending from the top of said container.

In testimony whereof, I have hereunto set my hand.
